any one know how to find out when a motor was re-built? when i bought my truck the dealer had just gotten it in and was still in the process of cleaning it when i bought it. so i assume thy didn't look it over to well because he told me it had 245K on it, but after getting it home and looking over the motor more i saw many Navistar re manufactured stickers all over it. problem is i have nothing else to go by, the motors wiring harness is dated for 2004 but thats about it. any thing I'm overlooking here?? called Ford and Navistar, no luck there. buddy of mine at work said there should be a tag or something written on it, but still no luck-maybe I'm looking in the wrong spot. any help would be great, it would be nice to know when it was rebuilt so i can figure what miles it has.
